Michigan's One-Year PIP Filing Deadline: What MCL 500.3145 Actually Costs You
| What is Michigan's one-year filing deadline for No-Fault PIP benefits? | |
|---|---|
| Under MCL 500.3145(1), Michigan accident victims must either file a lawsuit for No-Fault Personal Injury Protection (PIP) benefits or give written notice of injury to their insurer within one year of the accident date. Miss both, and your right to collect PIP benefits is permanently extinguished, even for medical bills you have already paid and treatments you have already received. The second rule, known as the one-year-back rule, applies even when you file on time: you can only recover expenses incurred within the one year preceding your filing date. PIP benefits cover medical expenses, lost wages for up to three years, replacement services, and attendant care. Two narrow exceptions exist: (1) if you provided written notice of injury to your insurer within one year and (2) if your insurer previously made any PIP payment on your claim. If you are approaching one year from your accident date, contact Christopher Trainor & Associates at the Michigan Legal Center (248) 886-8650 immediately. |
The Deadline Nobody Told You About
This article explains a crucial, often-missed legal deadline for Michigan accident victims: the requirement to file for No-Fault Personal Injury Protection (PIP) benefits within one year (MCL 500.3145(1)).
We will explain what this deadline entails, the types of benefits it governs, common pitfalls that lead individuals to miss it, and crucial exceptions that may preserve your claim. Understanding this deadline is vital, because missing this narrow window can permanently prevent you from receiving crucial financial recovery.
This piece exists because you should not have to find out the hard way. We encourage you to read this information carefully and share it with those who might benefit. If your accident occurred within the last twelve months, contacting the Michigan Legal Center promptly can help protect your rights.
Please note: This article provides general information only and is not legal advice. Michigan No-Fault law is highly complex and varies significantly based on individual circumstances. For personalized legal guidance regarding your unique situation, it is crucial to consult directly with a qualified attorney.
What MCL 500.3145 Actually Says
Under Michigan's No-Fault law, your auto insurance must pay for your Personal Injury Protection (PIP) benefits. These benefits cover your accident-related medical expenses, lost wages, and certain other costs, regardless of who caused the crash. These benefits are not optional; you are entitled to them through your insurance contract and premium payments. They are part of every auto insurance policy in Michigan.

MCL 500.3145(1) governs the duration for which the funds can be collected. So, what does this legal text mean for you? In plain language, it means three things:
| MCL 500.3145(1) - Statute Text |
|---|
| An action for recovery of personal protection insurance benefits payable under this chapter for accidental bodily injury may not be commenced later than 1 year after the date of the accident causing the injury unless written notice of injury as provided herein has been given to the insurer within 1 year after the accident or unless the insurer has previously made a payment of personal protection insurance benefits for the injury. If notice has been given or a payment has been made, the action may be commenced at any time within 1 year after the most recent allowable expense, work loss, or survivor's loss has been incurred. |
In plain language, this means three things:
One year from the date of your accident, you must either file a lawsuit for PIP benefits or give written notice of your injury to your insurer within one year of your accident date. Fail to do both, and your PIP claim is lost.
Two narrow exceptions can extend the deadline: written notice of injury given to your insurer within one year or a prior PIP payment made by your insurer. Either one resets the clock to one year from the most recent expense incurred.
Even if you file on time, a separate provision called the one-year-back rule limits what you can recover to the expenses incurred in the twelve months before your filing date.
| Two Rules. One Statute. Both Can Hurt You. |
|---|
| Most people hear about the one-year filing deadline and assume that filing within 12 months is sufficient. What they do not realize is that the one-year-back rule operates independently of the other rules. You can file on time and still lose significant benefits because you waited too long to file within that year. Both rules require attention from the day of the accident onwards. |
Which Benefits Does This Deadline Govern?
Every No-Fault PIP benefit is subject to this deadline. These are not secondary or optional benefits. They are the core of what Michigan's No-Fault system promises you after an accident.
MCL 500.3107(1)(a) -- Medical Expenses
All reasonably necessary products, services, and accommodations for your care, recovery, and rehabilitation. This covers emergency room visits, hospital stays, surgical procedures, physical and occupational therapy, prescription medications, medical equipment, in-home nursing care, and any other treatment related to your accident injuries. There is no dollar cap on medical benefits for accidents before June 11, 2019, under unlimited PIP policies, and coverage depends on the elected PIP tier for accidents after that date.
MCL 500.3107(1)(b) -- Work Loss
Up to three years of income replacement if your injuries prevent you from working due to your injuries. Benefits are paid at 85 percent of your gross income, subject to a monthly maximum that adjusts annually. If your injuries affect your ability to work for months or years, this is often the largest component of your PIP claim, and it is fully subject to the one-year filing rule in Michigan.
MCL 500.3107(1)(c) -- Replacement Services
Up to $20 per day, for up to three years, for services you would ordinarily have performed for your household but cannot because of your injuries, including lawn care, cleaning, childcare, grocery shopping, and home maintenance. These are compensable under PIP. Many accident victims never claim them simply because no one has told them they could.
Attendant Care
If your injuries require another person to assist you with daily living activities, those care hours are compensable under PIP. A professional agency or, in many cases, family members can provide attendant care. The rate and documentation requirements are significant. This is an area where insurers frequently underpay or deny claims without legal counsel.
MCL 500.3108 -- Survivor's Loss
If a person dies from their accident injuries, their dependents may claim survivor's loss benefits, covering the contributions the deceased would have made to the household. These benefits are similarly governed by a one-year rule.
The Rule Inside the Rule: Michigan's One-Year-Back Limitation
You must file within one year of your accident. But that alone is not enough.
Even when you meet the filing deadline, MCL 500.3145(1) contains a second restriction: you can only recover expenses incurred in the one year immediately before your filing date. Any expenses incurred more than twelve months prior to your filing date are permanently unrecoverable.
This is the one-year-back rule, which was firmly enforced by the Michigan Supreme Court in Devillers v. Auto Club Insurance Ass'n, 473 Mich 562 (2005). Before Devillers, Michigan courts interpreted the statute more generously. After Devillers, this rule became a strict mathematical cutoff.
| How the One-Year-Back Rule Works in Practice |
|---|
| For example, if you were injured in an accident on January 1. You began treatment in January, February, or March. You then filed your PIP lawsuit on December 15 of the same year, 11 months after the accident. You have filed within one year. However, the one-year-back rule means that you can only recover expenses from December 15 of the previous year. You had no expenses before January 1 of the accident year; therefore, in this example, you are fine. Now consider the following scenario: you wait 14 months to file a claim because your insurer is covering your bills, and you do not realize that you need to file a lawsuit. Under MCL 500.3145(1), you have missed the filing deadline entirely unless you provided written notice or your insurer made payments. However, even if a payment was made and the deadline was extended, the one-year-back rule meant that any expenses from more than one year before the filing date were unrecoverable. The longer you wait, the more you leave on the table. |
The Timeline That Determines Everything
This is what the one-year window looks like for a typical Michigan accident victim and where it goes wrong:
Month 1: Accident
The accident occurs. The one-year clock under MCL 500.3145(1) starts immediately after the accident. Most people are unaware of this.
Months 1-3: Treatment
ER visits, diagnoses, and initial treatments. The insurer begins paying PIP bills. Because the insurer is paying, many victims assume that their claims are protected. It is not. A PIP payment extends the window only if and when the payment is made.
Months 4-8: Recovery
Physical therapy, specialist appointments, and work loss. While focusing on recovery, it's crucial to remember the approaching one-year deadline, as insurers typically do not provide reminders.
Month 9: Warning Zone
If you have not given written notice or filed, you have approximately 90 days remaining. If your insurer stops paying benefits at any point and no notice is given, the window may already be closing.
Month 11: Critical
One-year-back rule is now active. If you file today, you can only recover expenses from this month. Every week you wait costs you a recoverable history.
Month 12: Deadline
Unless you provide written notice or the insurer makes a qualifying payment, your right to file a PIP lawsuit will expire. After this date, courts will dismiss your PIP claims. This deadline is jurisdictional in nature. It does not bend for hardship.
Month 13+: After Deadline
Without an applicable exception, PIP benefits are permanently barred from being paid. You cannot recover past medical bills, outstanding treatment, or future care under No-Fault, even if your injuries are severe and ongoing.
Why Michigan Accident Victims Miss This Deadline
The one-year rule is not buried in the fine print. It is embedded in the statute that governs every No-Fault policy sold in Michigan. However, the gap between what the law says and what accident victims know is vast, and that gap costs people real money.
Here's why this gap consistently leads to problems:
| The Reasons People Miss the Deadline | What the Insurance Company Knows |
|---|---|
| The insurer is paying bills, so the victim assumes everything is handled | Adjusters are trained to keep claimants engaged without acknowledging the deadline |
| No one explains that paying bills is different from protecting your legal right to collect future benefits | Every month that passes without a filing reduces the insurer's exposure under the one-year-back rule |
| Recovery requires all available mental and physical energy. Legal deadlines are not at the forefront of their minds. | A missed deadline ends a PIP claim permanently, with no legal recourse |
| Treating physicians and hospital billing departments do not mention it | The insurer has no legal obligation to inform you of the deadline |
| The insurer's adjuster calls frequently but never mentions the filing deadline | Quick, low settlements offered in month 10 or 11 are often timed deliberately |
| People assume the three-year statute of limitations applies, not realizing No-Fault has its own shorter rule | Insurance companies internally track deadlines. You should too. |
| Injuries worsen after month nine, creating new costs just as the window closes | This information asymmetry is one of the most consequential features of Michigan No-Fault litigation |
This is not abstract. We have spoken with people who received medical treatment for months, believed their insurer was handling everything, and called us in the thirteenth month to ask why their bills were suddenly being denied. By then, the deadline had passed. This is one of the most difficult conversations to have.
The Two Exceptions That May Still Protect You
MCL 500.3145(1) is not an absolute bar in all situations. Two exceptions can preserve your right to collect PIP benefits beyond the one-year mark, but both are narrow. Neither is automatic. Both require a legal analysis of specific facts.
Exception One: Written Notice of Injury
If you provided written notice of your injury to your insurer within one year of the accident, you were not required to file a lawsuit within that same year. In both scenarios (timely written notice or prior PIP payment) the filing deadline is extended to one year from the date the most recent allowable expense, work loss, or survivor's loss was incurred.
This means that the filing deadline effectively rolls forward as long as new compensable expenses continue to accrue. If your treatment is ongoing and you provide written notice in time, your window for collection may extend significantly beyond the original one-year mark.
| What Counts as a Written Notice? |
|---|
| Written notice must be given to the insurer and the fact of the injury must be communicated. The statute does not require a specific form, but the notice must be written and directed to the insurer. Verbal phone calls are not qualified. A formal claim submission typically satisfies this requirement; however, if you are relying on a specific document as your written notice, an attorney should review it before you assume protection. If you are unsure whether your communications with your insurer constitute written notice under MCL 500.3145(1), do not make a guess. Call Christopher Trainor & Associates from the Michigan Legal Center at (248) 886-8650. The analysis takes a few minutes. The stakes are high. |
Exception Two: Prior Payment of PIP Benefits
If your insurer has previously made any payment of No-Fault PIP benefits for your injury, the one-year filing requirement is modified in the same way: you have until one year after the most recent allowable expense, work loss, or survivor's loss is incurred.
This is the exception on which most accident victims inadvertently rely without knowing it. If your insurer paid even one medical bill under PIP, that payment triggers an exception. The window remains open as long as compensable expenses continue.
| The Critical Trap Inside Exception Two |
|---|
| The prior payment exception does not protect you if your insurer stops making payments. If your insurer paid bills through month six and then denied further coverage, your protection under this exception extends only to one year from the last expense incurred while payments were active. Subsequently, if no lawsuit has been filed and no written notice is given, the deadline can still expire. The moment your insurer denies, delays, or suspends PIP payments, you should treat that date as the start of your critical period. Ongoing protection should not be assumed. Get an attorney involved immediately. |
What Happens If You Miss the Deadline
Michigan courts strictly enforce MCL 500.3145(1). The Michigan Supreme Court's 2005 decision in Devillers v. Auto Club Insurance Ass'n, 473 Mich 562, ended the more flexible approach that had developed in intermediate appellate courts. After Devillers, equitable tolling arguments were largely rejected. Neither hardship, ignorance of the law, nor the severity of injuries will toll these deadlines.
If you miss the one-year filing rule without an applicable exception, a court will dismiss your PIP claims. You lose the right to recover:
- Unpaid or unreimbursed medical bills already incurred
- Ongoing treatment costs for injuries that continue after the deadline
- Future surgical or rehabilitative care tied to your accident
- Work loss benefits for income you have already lost
- Work loss for reduced capacity you will experience going forward
- Replacement services and attendant care, past and future
- Any other No-Fault benefit governed by MCL 500.3145(1)
This does not necessarily end your entire case. If you have a viable third-party claim against the at-fault driver for pain and suffering under MCL 500.3135, that claim runs on the three-year statute of limitations under MCL 600.5805 and is separate from your PIP claim. However, the PIP benefits, the first-party benefits from your own insurer that you paid for through your premiums, are gone.
This distinction is crucial, especially when injuries are severe, the at-fault driver is uninsured, or PIP benefits are your primary source of recovery.
| 1 YEAR | from the accident date. This is all you need to file or provide written notice. No exceptions for hardship. No extensions for not knowing. |
|---|
| $0 | is what you recover in PIP benefits if the deadline passes and no exception applies. Your premiums paid for those benefits. A missed deadline takes them away. |
|---|
The one-year rule and the three-year statute are two separate clocks running at the same time.
The one-year deadline under MCL 500.3145(1) governs your PIP claim, the benefits you collect from your own insurer. The three-year statute of limitations under MCL 600.5805 governs your third-party claim against the at-fault driver, if your injuries meet the serious impairment threshold under MCL 500.3135.
They are different claims, different defendants, and different legal standards. Missing one does not automatically kill the other -- but both clocks start on the date of the accident.
For a full breakdown of how these two claims work together -- what each covers, when you need both, and what happens if you settle one without protecting the other -- read: The Difference Between a PIP Claim and a Third-Party Claim in Michigan.
What to Do Right Now If You Are Within One Year of an Accident
If you are reading this and your accident occurred within the last 12 months, there are specific actions you should take today. Not next week. Today.
Determine exactly when your accident occurred. The one-year clock runs from that date. Calculate the number of days remaining. Write it down.
Locate all written communications sent to your insurer. Any letter, email, or claim form that notified your insurer of your injury in writing may constitute written notice under MCL 500.3145(1). This may be your most important protective document.
Confirm whether your insurer has made any PIP payments on your claim. If they have paid even one medical bill under your No-Fault policy, you may fall within the prior payment exception. Pull your records and confirm this in writing.
Do not wait for your medical treatment to conclude before consulting an attorney. Treatment timelines and legal deadlines are independent of each other. You can consult an attorney to protect your claim rights while continuing to receive care.
Call Christopher Trainor & Associates from the Michigan Legal Center at (248) 886-8650 today. We will review your claim timeline, identify whether any exceptions apply, and take the necessary steps to protect your benefits before the deadline. Consultations are free of charge. It takes less than one insurance phone call. It may be the most important legal decision you make in the next 12 months.
Why This Deadline Matters So Much to Us
The one-year rule is not a technicality. This is the mechanism by which insurance companies permanently close valid claims without ever having to prove that the claims are wrong.
We have talked to people who spent eleven months doing everything right, recovered from serious injuries, kept every receipt and medical record, and still lost their PIP benefits because no one told them the deadline existed. Their injuries were real and serious. Their bills were real. Their losses were real. And the law still barred their recovery.
However, this outcome is preventable. It requires knowing that the rule exists and acting before the window closes. This is exactly why Christopher Trainor and his team at the Michigan Legal Center review No-Fault claim timelines from the first conversation we have with a new client.
Michigan No-Fault law is genuinely complicated. The 2019 reform (PA 21 of 2019) added new PIP coverage tiers, new coordination rules, and new disputes between insurers about which policy pays first. The one-year rule sits at the center of all of it. It does not care how complicated your situation is. It only considers the date on which the accident occurred.
We have recovered more than $300 million for Michigan accident victims, including in cases where the initial prognosis from an insurance adjuster was that the claim had no value. We know the worth of these cases. We know when the clock is running. We know how to stop it from running out on the people we represent.
| If You Are Within One Year of Your Accident, the Clock Is Still Running. |

| Call Christopher Trainor & Associates at the Michigan Legal Center before the deadline closes your claim. We have recovered more than $300 million for Michigan's accident victims. We know every provision of No-Fault law. More importantly, we know the cost of missing a deadline that was unknown. |

In summary, the one-year deadline for Michigan No-Fault PIP benefits is a strict and unforgiving rule that can have profound financial consequences for accident victims. While the law outlines specific exceptions, these are narrow and require careful legal analysis.
Proactive engagement with legal counsel is the most reliable way to navigate this complex landscape, ensuring your rights to medical expenses, lost wages, and other critical benefits are protected.
Do not let a lack of awareness jeopardize your recovery. Act promptly to secure the compensation you deserve.
Frequently Asked Questions
What is Michigan's one-year filing deadline for No-Fault PIP benefits?
Under MCL 500.3145(1), you must file a lawsuit for No-Fault PIP benefits or provide written notice of injury to your insurer within one year of your accident date. Miss both, and your right to collect PIP benefits is permanently extinguished. This deadline has been strictly enforced by Michigan courts since the Supreme Court's decision in Devillers v. Auto Club Insurance Ass'n, 473 Mich 562 (2005).
What is the one-year-back rule under the Michigan No-Fault law?
Even when you file within the one-year deadline, MCL 500.3145(1) contains a second limitation: you can only recover expenses incurred in the one year immediately preceding your filing date. Expenses older than 12 months before your filing date are not recoverable. This means that every week you delay filing your claim, you lose a week of potentially compensable expenses.
Are there exceptions to Michigan's one-year PIP filing deadline?
Yes, two. First, if you provide written notice of your injury to your insurer within one year of the accident, your filing deadline extends to one year from the most recent allowable expense, work loss, or survivor's loss incurred. Second, if your insurer previously made any PIP payment on your claim, the same extension applies to you. Neither exception is automatic or guaranteed. Both require specific facts to be applied, and both should be evaluated by an attorney before you assume that your claim is protected.
What PIP benefits does the one-year deadline apply to?
All of them. The deadline governs medical expenses under MCL 500.3107(1)(a), work loss under MCL 500.3107(1)(b), replacement services under MCL 500.3107(1)(c), attendant care, and survivor's loss under MCL 500.3108. Every benefit covered by your No-Fault policy is subject to this filing rule.
My insurer was paying my PIP bills. Does this protect me from the deadline?
It may be, under the prior payment exception. If your insurer made any PIP payment, that triggers an extension under MCL 500.3145(1). However, the protection runs only from the date of the most recent expense incurred, not indefinitely. If your insurer stopped paying benefits and you have not filed a lawsuit or given written notice, the window can still close. The moment your insurer denies or suspends payment, consult an attorney to assess your timeline.
How is the one-year PIP deadline different from Michigan's three-year statute of limitations?
The one-year rule under MCL 500.3145(1) governs your first-party PIP claim from your own insurer. The three-year statute under MCL 600.5805 governs third-party claims against the at-fault driver. They apply to different claims, different parties, and different types of damages. Both run from the accident date. For a full side-by-side breakdown, see The Difference Between a PIP Claim and a Third-Party Claim in Michigan.
What if I did not know about the one-year rule? Can I still file?
Following Devillers, ignorance of the deadline is not recognized as a basis for equitable tolling under Michigan law. Courts have strictly applied this rule, regardless of whether the claimant was aware of its existence. If the deadline has passed and no exception applies, courts will dismiss your PIP claims. This is why the most important thing you can do is contact an attorney before the deadline arrives, not after.
If I miss the PIP deadline, will I lose my entire car accident case?
Not necessarily. If the at-fault driver was negligent and your injuries meet the serious impairment of body function threshold under MCL 500.3135, your third-party tort claim may still be viable within the three-year statute of limitations. However, losing your PIP benefits means losing first-party recovery for medical expenses, lost wages, and other out-of-pocket costs. The financial impact depends on your specific injuries and coverage.
